TL;DR: In this article, the advances in the materials selection for applications in structures and engines of current and future supersonic aircrafts are reviewed, and a new materials selection chart is presented that would enable aerospace designers to select appropriate materials for application in high-performance current and hypersonic aircraft.

TL;DR: In this paper, the authors used an optical microscope linked with a computerized imaging system using MSQ software to detect three types of inclusions: Al−Cu, Al-Cu-Fe, Al−Fe-Fe-Si−Mn, and Al−Si-Mn enriched regions.

TL;DR: In this article, a comparative analysis of effects of cold working (CW) and annealing on tensile and impact-toughness behavior of 7075 Al alloy was performed. And it was found that cold rolling has a significant effect on decreasing the impact toughness of alloy that enhance with amount of CW; this loss in impact energy could not be compensated by recrystallization process.

TL;DR: In this paper, the failed gas-turbine blades (first stage blades) were acquired from TNB Research Sdn. Bhd: a subsidiary of Malaysian power-generation industry (TNB, Malaysia).

TL;DR: In this article, a powder metallurgy (P/M) superalloy turbine blades are increasingly being used in jet-aircraft engines, and the improvement in creep strength is ensured though microstructural control achieved by developing a suitable heat treatment process.
